| Abstract: | A linearized method to solve the rectangular fin surface heat transfer involving radiation' convection and conduction is given. By using the linearized analysis, the nonlinearizing partial differential equations are solved. The commons effect on n of radiation and convection is analysed, the formulas for calculating the heat loss. of fins correspond\ing to simultaneous radiation and convection are proposed. |
